Well, I feel I look very similar still to how I did in middle school, especially with regards to my face. I am pretty sure I had naturally lower T for whatever reasons (I have read that some TS have an exaggerated androgen receptor, resulting in lower levels of masculinity). My little brother (year and a half younger) and I always looked completely different. He was always big, muscular, a football player, huge wrists and hands etc. whereas I have never been over 145 pounds in my life and have much more feminine features in general. Why the difference? Well, it is hard to say genetics wasn't at least a significant factor but it would not surprise me in the least to find out I had very low levels of T since we always ate the exact same food and did similar activities (we both are extremely athletic). I was never very aggressive or angry either and honestly didn't feel a change really at all aside from the increased emotions when going on HRT.
